Last week, NASA astronaut and Waterbury native Rick Mastracchio blasted off into space and boarded the International Space Station. On Wednesday afternoon, he tweeted a photo of his home state from the ISS. He said the station's altitude is around 400 km, and the view is magnificent.

Mastracchio also responded to a few adoring space geeks.

@jannlett Sleeping on board the ISS is great. We have a very small closet to hang our sleeping bag in and our personal gear and PC.

It may be tough to see him, but you do have opportunities to see the ISS from Earth. NASA says it's the third brightest object in the sky. You can also sign up for email alerts that will tell you when the ISS is overhead and when you might be able to see it.
